Poops all night?

So, my babe is kinda driving me nuts. My other babe never did this. Anywho, he wakes up because he poops or is wet. I change him and then nurse him, swaddle him up and then he poops again! Unwaddle him change his diaper, swaddle him back up lay him down..15 minutes later poops again! This is like all night long! He doesn't poop much. Maybe the size of a dime. Help! How can I stop this? Maybe something in my diet? He was premature born at 35 weeks and is now 2 weeks old.
